FPECIFICATION forming part of Letters Patent No. 744,844, dated November 24, 1903.

Application iiled May 22, 1903. Serial No. 158,334. (No model.)

` To all whom it may concern:

, provided on its outerend at iis center with Be it known that I, MARTIN F. WIEDEMANN, i a resident of Burlington, in the county of Des I Moines and State of Iowa, have invented certain new and useful Improvements in Awnings; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Myinvention relates to an improvement in awnings, and more particularly to improved center and end supports for the awning-pole roller, and, further, to provide improvements on the construction disclosed in my application for patent filed March 10, 1903, Serial No. 147,121; and with these objects in view the invention consists in certain novel features of construction and combinations 'and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure lis a view in elevation illustrating my improvements. Figs. 2, 3, and 4 are enlarged views illustrating the center support, and Figs. 5, 6, 7, and S are views of modified forms of end bearings.

1 represents the awning pole or roller, to which the awning is secured and is adapted to roil or be wound thereon. This awning pole or roller 1 is of wood or metal, as preferred, and is housed at both ends in cylindrical metal cups 3, said cups having internal longitudinal flanges or keys ,4a to enter grooves in roller 1 and compel the cups and roller to turn together. The cup 3, at one end of roller 1, is made with an integral sprocketwheel 4, over which an endless sprocket-chain 5 passes and is driven as described in detail in application Serial No. 147,121, and hence need not here be described. Each cup 3 is an integral journal or trunnion 6, mounted in a bearing 7 in a bracket 8, secured to the wall or other support, andthe journals 6 are made withannular grooves forming runways for balls 9, inserted through a plugged opening 10 in the bearing, and provide a ball-bearing for the journal or trunnion and insure the easy turning of roller or pole 1.

The roller or pole 1 is supported at its center by my improvements, which will now be described.

A plate 11 is secured to the wall or other support in any approved manner and is provided at opposite ends with openings 12 to receive crossbars 13 on the inner ends of curved arms 14, two of which are located at each end, one an upper and the other alower arm, as will hereinafter appear. Lugs 15 project over the lower portions vof the openings 12 to lock the cross-`|oars in the openings when moved down behind the lugs, and the upper pair of arms have notches 16 in their inner ends, which when in position are below the lugs 15 and are adapted to receive keys 17 to permit them to be locked in place, preventing their upward movement andremoval until the keys are displaced, and as the upper arms are directly above and against the lower arms at their inner ends the lower arms cannot be removed until the upper arms are first removed, and the keys therefor secure both pairs of arms in place. The lower pair of arms 14E provide roller-bearings for the trunnioned ends of two rollers 18, on which the pole or roller 1 is supported, and the Lipper pair of arms at their outer ends provide rollerbearings for the trunnioned ends of a roller 19, which contracts the opening between the arms to prevent the escape of the awningpole and also serves to guide the awning onto the pole.

In the modified form of end bearing shown in Figs. 5 and (5 neither the journal norl bearing is grooved, and rollers 2O are mounted between the journal and bearing and are supported at their ends in rings 21 around the journals, but of sufficient internal diameter to prevent contact with the journal.

In the modification shown in Figs. 7 and 8 a journal-box 23, having an angular opening, is provided. This angular opening is adapted to receive half bearingblocks 22, which fit the angular opening and have semicircular bearing-faces for the journal. The bearingfaces and journal are both grooved to provide cooperating runways for ball-bearings 9, and the balls and bearing-blocks are assembled on the journal before the latter are inserted in the angular opening in the journalbox.

IOO

A great many other changes might be made in the general form and arrangement of the parts described without departing from my invention, and. hence I do not confine myself to the precise details set forth, but consider myself at liberty to make such slightchanges and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire'to secure by Letters Patent, is-

l. A center bearing for awning rollers or poles, comprising a plate to be secured to a support and having openings therein and lugs projecting over the openings, arms, crossbars on the inner ends of the arms to enter the openings in said plate and lock behind the lugs thereon, and rollers carried by said arms to support the awning pole or roller.

l2. A center bearing for awning rollers or poles, comprising a plate to be secured to a support and having four openings therein and lugs projecting over the lower portions of said openings, two pairs of arms having cross-bars at their inner ends to enter the openings and which are disposed behind the lugs when the arms are moved downward,

, keys to enter notches in the upper pair of arms below the lugs and lock the arms in the MARTIN F. W IEDEMANN.
